OSTEOPATHIC-TREATMENT CHAIR.

To all whom it may concern:

Be it known that I, TELL J. BERGGREN, a subject of the Kingdom ofSweden, residing at Battle Creek, in the county of Calhoun and State ofMichigan, have invented certain new and useful Improvements inOsteopathic-Treatment Chairs, of which the following is a specification.

This invention relates to treatment chairs especially adapted forosteopathic practice, and has for its object, improvements in that classof apparatus which can be adjusted in different positions for thetreatment of the varying conditions of patients. For this purpose Icontemplate, in combination with an adjustable-back reclining chair, asuitable foot and leg-engaging holder arranged at the forward portionthereof whereby the subject undergoing treatment may, in the event ofreclining in an extreme backward position, catch the feet and beprevented from careening or falling from the chair. I also contemplate,in combination with a chair of the class described, providing at eitherforward lower side thereof a stirrup for the purpose of engaging thefeet, whereby a subject undergoing certain backward or side inclinationswill be held to the chair while thus undergoing treatment. There arealso other improvements in the details which will be pointed out in thespecification and claims.

In the drawings forming a part of this specification, Figure 1 shows aside view of the chair, the dotted lines illustrating some of thevarious positions to which the back and the leg-holding bracket may beadjusted. Fig. 2 is a plan View of the chair. Fig. 3 is a rear view.Figs. 4 and 5 are detail sectional views of the leg-holding bracket linkadjustment, Fig. 4 being a cross section of Fig. 5 on the line m.r. Fig.(3 is a side view of the chair with a modified form of leg-holdingdevice Fig. 7 is a broken plan view.

In the drawings, like marks of reference refer to corresponding partsthroughout the different views, in which A, represents the chair seat,B, the adjustable reclining back, and O, the adjustable leg-holdingbracket.

The chair seat may be supported in any ordinary and convenient manner,and as illustrated is mounted 011 the four legs, 1, arranged in nearlyequilateral positions to the chair seat, as shown. Connecting theSpecification of Letters Patent.

legs on either side thereof and near the lower extremities thereof,rungs or connecting braces, 2, are provided, and to each of these rungs.and near the front legs of the chair, foot-stirrups, 3, are attached.

To the seat of the chair at the rear thereof, the back, B, is hinged onpintles, 4, and to the sides of the back standards, quadrants, 5, areattached. These quadrants are adjustably secured in the variouspositions to which they are adapted to be placed, by means of a headedand screw-threaded clamping rod, 6, and correspondinglythreaded handwheel, 7, run onto the threaded end of the rod in the ordinary manner,the rod in the present instance passing through the rear legs of thechair and through slots 8 within the respective quadrants, as shown.This quadrant, by preference, is marked with the degrees of a circle andis intended, in connection with the adjustment to which the back, B, maybe placed, to afford a means whereby any special degree of attitude maybe given a patient or subject undergoing treatment while in the chair.It also affords a means for regulating the angular adjustment of thechair back from day to day by degrees or fractions thereof, as may bedeemed expedient in the treatment of a patient, and by keeping data ofthe preceding day on which a patient has undergone treatment, theadjustment may be regulated to suit the occasion, either up or down onthe quadrant.

To the forward portion of the chair, a leg or foot-holding bracket, 0,is attached. By preference this bracket is T shaped, as shown in Figs. 2and 7, the top or crosshead, 9 bein situated above and forward of thechair seat and in parallel arrangement with the forward edge thereof.This head piece. is attached to the upper ends of the staiulards, 10,which in turn are pivotally attached and capable of backward and forwardmovement, with respect to the chair, on a cross-bar 11 connecting thefront legs of a chair, as shown. Near the upper portion of the bracketand hinged below the cross-head 9, an adjustin llnk 12 is provided. Thefree end of th1s link extends below the forward central portion of thechair seat, and is received through eyelets 13 formed on a bracket 14attached to the undersides of the chair. Between the aforesaid eyeletsand about the free end of said link, an eyelet 15 formed on a clampingrod 16, is

fitted. The free end of this clamping rod is screw-threaded and passesthrough the side of the chair seat and is fitted with a correspondinglyscrew-threaded hand wheel or nut 17, by which means the link may besecured in various adjustments necessary and expedient for regulatingthe pitch of the leg or foot-holding bracket.

In lieu of the pivotally-hinged leg-holding bracket before described, Ihave shown, in Figs. 6 and 7, a leg or foot-holding bracket, C, capableof backward and forward adjustment with respect to the chair, in amodified form. In this instance the cross-head 9 is attached to theupper curved extremities of the longitudinally-adjustable slottedsliding members 18, which pass between the front legs of the chair overthecross supports 19 below the chair seat, and to the outer sides of theparallel seat sup ports, 20. That the leg-holder may be secured in thevarious positions to which it may be expedient that it be adjusted, aheaded clamping bolt 21 passes through the supports 20 through slots 22,in the members 18, and a threaded end thereof extends through the sideof the chair seat and is fitted with a correspondingly-threaded handwheel 23, by which means the slotted members 18 may be clamped in theiradjustment to the supports 20.

In operation, the subject requiring treatment for certain ailments ofthe leg, back and abdominal muscles, and for correcting certain spinalafl'ections, lies upon the back with the feet engaged below the T-headof the leg-holding bracket, 0; in this position, the

- adjustable back,B,of the chair, maybe regulated to suit the occasion,the degree of angularity may be either up or down and in either case thedegree of position may be observed and regulated from day to day as thecondition of the patient under treatment may require. With the feet ofthe patient engaging the leg-holding bracket, the operator may also workthe arms, head and neck of the subject in various attitudes without fearof causing the subject to roll or fall from the chair.

lVhen it is expedient that abdominal, back and other muscles shouldundergo stress of peculiar side or pivotal movements with respect to thehips, or backward movement in connection with the side and pivotalmovement, the feet of the subject are placed Within the stirrups 3,which will prevent the subject from losing hold of the chair duringtreatment.

Various modifications in detail may be re I sorted to without detractingfrom the essence or departing from the spirit of the in vention.

Having, therefore, set forth the objects and purposes of my invention,what I claim 1s:--

1. In an article of the class described, the combination with a chair,of a leg-securing holder arranged forward of and above the plane of thechair seat, said holder comprising a transverse foot securing head piecehaving a standard pivoted to the lower forward portion of said chair, asand for the purpose set forth.

2. In an article of the class described, the combination with a chair,of a leg-securing holder arranged forward of and above the plane of thechair seat, said holder comprising a transverse foot securing head piecehaving a standard plvoted at or near the lower forward portion of saidchair and TELL J. BERGGREN.
